INSIGHT

25D Variants and Testing Gaps

  • There are many forms of 25D vitamin D molecules, some of which are not routinely measured.
  • The body produces non-calcium-influencing forms in disease states that lab tests often miss, leading to false deficiency diagnoses.
ADVICE

Vitamin D Seasonality Advice

  • Don't panic about vitamin D storage drop during winter; it naturally fluctuates seasonally.
  • The active form remains stable year-round, supporting immune function regardless of season.
ADVICE

Study Design for Vitamin D Effects

  • Research should focus on radiolabeling vitamin D molecules in patients benefiting from high doses.
  • This could clarify mechanisms and why some respond or are harmed by treatments like MS vitamin D protocols.
